The Sentry dashboard was empty for months — here's why (and the 2-line fix that mattered most)

This is a submission for DEV's Summer Bug Smash: Clear the Lineup powered by Sentry. Project Overview This backend powers K-XpertAI, the AI coding assistant at the center of KingxTech's developer-tools ecosystem — a chat-first assistant that turns a prompt into working code in a live artifact panel, with SynthCode IDE as the editor you take it into next.

Building SignalHQ: Engineering a Production-Grade Incident Management Platform from Scratch

Most portfolio projects stop after implementing authentication and CRUD operations. Production software doesn't. Engineering teams need systems capable of handling operational failures under pressure. During an incident, dozens of engineers may collaborate simultaneously, permissions must be enforced correctly, every action must be recorded, and changes must propagate instantly across every conn...

Stop Using `useEffect` for Data Fetching—Please, I Beg You

The Scene It's 2 AM. You're staring at your screen, debugging why your dashboard keeps showing yesterday's data even after you've changed the filter. Your useEffect dependency array looks like a crime scene. You've got three useState hooks just to manage loading, error, and data. You added a cleanup function, but somehow the component still throws that dreaded warning: "Can't perform a ...

When Impressive Code Isn't Actually Working: A Vibe Coding Epiphany

- The Setup I've been working on a semantic recall application called VaultAI for AI tools and prompts I've previously used and needed to remember, and somewhere along the way, I realised that I've relied too much on "vibe coding" (describing what I want to code and mostly letting the AI generate the actual implementation) to create a chatbot for recalling those entries via a prompt This has ult...

That CORS error? It wasn't my code

I learned something interesting while debugging Apache, Express, and CORS. Seeing a CORS error in the browser doesn't necessarily mean your Express CORS configuration is broken. I had a frontend sending requests to an API through Apache: Frontend → Browser → Apache → Express (server.js) The browser was showing a CORS error. My first thought was naturally: “Something must be wrong with my CORS conf...

Image-layer prompt injection: measuring a defense across 108,015 samples

Most prompt injection defenses guard the text prompt. They inspect the user's message, sometimes the retrieved documents, and they assume everything else arriving at the model is inert data. For a multimodal model that assumption is wrong. The model reads the image too, and an image is a large, high-entropy container that a human reviewer looks at for half a second and waves through. You can hide...
